    Standard zinc alloys are stronger than aluminum and magnesium alloys at room temperature. Strength is inherent in the alloy itself and does not require secondary processing like most aluminum alloys—this saves on the overall cost per part. EZAC is an alloy offered by Dynacast that is stronger and harder than any other die casting alloy.
